I respect ur opinion but she was upset about seung ah lying and when she saw him in mujin's bed and well ofcourse half naked she might have though something happend between them thats when she realised seung ah wasnt really asexual especially when mujin said (she doenst know anything) she asked seung ah again if what she know is the truth but she has already doubts about it but seriously none of this wouldve happend if seung ah just told do_gyeom the truth but he was to late he broke his trust with do_gyeom thats why do_gyeom really didnt take his confession srsly😓
